Ford Forum - Enthusiast Forums for Ford Owners

i've changed (actually husband did it) the battery AND the alternator and put both brand new ones in. my truck runs fine and doesn't cut off but the battery light is still on. i'm really scared it could be something more serious and could possibly damaged my new battery and alternator i just bought. i have a 2004 ford explorer.

any suggestions?

a friend told me something about a "diode module" and replacing that and that the part should cost less than $20.
